Chemical containers 12I tre.. removably supportedxmthe cylindlsl bymeansef a ro- Qlyxgre'ater fI-Vulils` 'thanthe radius ofcylindersfin'orderthat the vmember Will'ofer no provided with acentrally disposed bearing" lug 16, while at the lower ends of thecylin- 1 ders is a similar bearing lug 17, the boresvof both lugs beingin alinement. Mountedin the bores of lugs 16, 17 is a shaft 18 thatextends beyond the upper surface of the cover member to which isrigidlysecured'in anypsuitable manner alhand wheel 19 preferably. formedof bakelite or other non-corrodible substances. f Mounted on the lowerend of shaft 18, is

a double edged shearing knife 22, adapted when the arm is rotatedthroughthe medium Y' of the hand wheel 19 to successively form a slittedopening in each of the containers to expose the chemicals carriedthereby to the action of the water flowing` through the device. i Y iFrom the above it is thoughtrthat the operation of the device will beobvious. loading the cylinders with filled containers the cover memberis unscrewed and upended. The rotatable member 14C isthen turned untilits segmental openings register with the open ends of the cylinders topermitthe insertion of the chemical containers in the cylinders, themember being again rotated over the open ends of the cylinders tosupportthe containers in position. Cover member is then inserted in thecasing and secured thereto. When a person desires to obtain `aperfumedbath or shower, the hand wheel is rotated to force the shearingknife 22 into engagementwith one of the sealed cylinders to form alateral cut therein to expose the chemical therein to the action of thefluid flowing through the device. vTheV content-sof one container willusually be sufficient to perfume or chemicalize a bath or shower ofusual duration. Additional baths or vshowers maybe obtained until allthe containers .are emptied, when Y fresh ones may be inserted` As in mypatent above referred to the chemicals employed are for the purpose ofsoftening the water, or perfuming the same, and as the salts employedare readily soluble all danger of clogging the device is obviated.

As the chemical containers are formed of inexpensive materials as wellas the chemicalsf employed, it will be apparent that the same may bevended at slight cost.

What I claim is: A

L1.A device of the class described comprising a casing having'fiuid inletand outletY openings the inlet opening adapted to be connected to asource of fluid supply, a sealed paper cylinderV for holding a chemicaldetachably mountedin said casing, and a manually operated shearing knifeVmounted in said casing for forming an opening in a fluid inlet andYoutlet openings adjacent the bottom of said casing, the inlet adapted tobe Vconnected to a source of fluid pressure, a clo-v v sure for theupper endof said casing having Y a depending cylindrical casing havingan open lower end for the reception of 'a chemi- Y cal container, meansto support the container in said cylindrical casing, a container cuttinknife carried said casing closure `an means for rotating the knifeto'cut the container yfor releasingthe chemicals contained therein toimpregnate the fluid as it passes through the casing.

6. A device of theclass described comprisingv a casing having fluidinlet and outlet openings,l said inlet opening adapted for connection toa'source of iiuid supply, the upper endof said-.casinghaving a removableclosure, a yplurality of chambers formed on the :underface of saidclosure forholding chemical containers, said containers being removable,means for supportmg'the containers in position iny said chambers, landrotatable means carried-by said closure for forming an opening in thecontainers successively to v release the chemical contained therein tothe action of the flowing Huid passingthrough the casing, whereby toimpregnate thefluid.

7. A deviceof the class described comprising a Casing open at its upperend and hav-A ing oppositely disposed fluid inlet and outlet openingsadjacent its lower end, said inlet opening adapted to be connected to asource of fluid pressure, a removable closure for said casing having aplurality of compartments open at their lower ends for the reception ofchemical containers, a rotatable shaft carried by said closure havingmeans on its upper end to rotate the same, a shearing knife carried bythe lower end of said shaft and extending transversely therefrom forsuccessively forming a cut in theV Wall of each of said chemicalcontainers to expose the chemicals carried thereby to the action of thefluid as it passes 'through the casing, and a flat circular memberhaving openings in its edge carried by said shaft for supporting. thechemical containers intheir compartments, said member adapted to berotated to move the openings therein into registerwith the open ends ofthe compartment to permit of the removal. of the empty containers andthe insertion of filled ones. v
